Mulching Plug

Instead of collecting grass clippings in a grass catcher, this mower has the option of recirculating the clippings back to the lawn. This is called mulching. Remove the grass catcher and the side-discharge chute from the mower, and operate with the mulching plug only for this purpose.

SECTION 5: OPERATING YOUR LAWN MOWER

WARNING: Read, understand, and follow all instructions and warnings on the machine and in this manual before operating.

NOTE: You must service the engine with oil and gasoline before starting the mower for the first time. Check oil and gasoline levels and fill up as necessary for subsequent starts.

Gas & Oil Fill-Up

Check oil level and add oil if necessary. Follow relevant instructions in the engine manual for this.

Service the engine with gasoline as instructed in the engine manual.

WARNING: Use extreme care when handling gasoline. Gasoline is extremely flammable and the vapors are explosive. Never fuel the machine indoors or while the engine is hot or running. Extinguish cigarettes, cigars, pipes and other sources of ignition.

WARNING: Be sure no one other than the operator is standing near the lawn mower while starting engine or operating mower.

WARNING: Never run engine indoors or in enclosed, poorly ventilated areas. Engine exhaust contains carbon monoxide, an odorless and deadly gas.

WARNING: Keep hands, feet, hair and loose clothing away from any moving parts on engine and lawn mower.

NOTE: See your engine manual packed with your unit for more detailed instructions.

Stopping Engine

Release blade control handle to stop the engine and the blade.

Disconnect spark plug wire and move away from spark plug to prevent accidental starting.

Before Starting Mower

Attach spark plug wire to spark plug. Make certain the metal cap on the end of the spark plug wire (inside the rubber boot) is fastened securely over the metal tip on the spark plug.

Starting Engine

Push primer three times. Wait about two seconds between each push. In cold weather around 55° F or below, prime five times. Do not prime to restart a warm engine after a short shutdown.

Standing behind the mower, depress the blade control handle and hold it against the upper handle.

Grasp starter handle and pull rope out slowly until engine reaches the start of compression cycle (rope will pull slightly harder at this point). Let the rope rewind slowly.

Pull rope with a rapid, continuous, full arm stroke. Keeping a firm grip on the starter handle, let the rope rewind slowly.

Using Your Lawn Mower

You can use your mower as a mulching mower or a rear bagger.

Be sure that the lawn is clear of stones, sticks, wire, or other objects which could damage lawn mower or engine.

WARNING: If the mower strikes a foreign object, stop the engine. Remove spark plug wire from the spark plug and thoroughly inspect for any damage. Repair the damage promptly before restarting and operating the mower.

For best results, do not cut wet grass. New grass or thick grass may require a narrower cut.

For a healthy lawn, always cut off one-third or less of the total length of the grass.
